  • EP 3 130 213 A1 relates to a measuring device for examining harvested grain for a combine harvester, which comprises a measuring chamber with an inlet and an outlet for a sample of harvested grain to be examined, the measuring chamber being designed such that the sample passes from the inlet into the measuring chamber and from there into the outlet during operation along a flow direction.
  • a transmission spectrometer is equipped with a first element in the form of a light source and a second element with a sensor for light that was generated by the light source and transmitted through the sample. The sensor is connected to an analyzer for wavelength-resolved analysis of the received light.
  • DE 10 2011 051 784 A1 discloses a method for operating a harvesting machine with an optical sensor, with which the processed area immediately behind the attachment is optically recorded in order to draw conclusions about the condition of the processed area.
  • a camera that is sensitive in the near infrared (NIR) is indicated as particularly suitable, since such a camera enables additional Analysis options for plant remains and soil can be used. For example, conclusions can be drawn about the water content of soil and/or plant remains.
  • One task may be to propose an agricultural harvesting machine that avoids the disadvantages of the state of the art.
  • the object is solved by the subject matter of claim 1.
  • the object is further solved by a method according to claim 7.
  • Embodiments are specified in the dependent claims.
  • the agricultural harvesting machine has a harvesting attachment with a mowing and intake device for cutting and picking up harvested crops.
  • a measuring device is provided for determining at least one property of the harvested crops, wherein the measuring device has at least one optical detection unit arranged on the harvesting machine behind the harvesting attachment and wherein the optical detection unit detects radiation reflected from plant stubble remaining in the soil.
  • the detection of reflected radiation from the plant stubble remaining in the soil has the advantage that the properties of the crop in the lower part of the plant can be determined and that additional growth can also be taken into account in the determination.
  • Determining the properties of the crop in the lower part of the plant i.e. in a plane in which the crop is cut, has the advantage that straw moisture can be determined as a property of the crop. Straw moisture is an important plant physiological characteristic that is particularly important for cutting the crop. Determining straw toughness therefore offers the particularly advantageous possibility of controlling the mowing device depending on the straw toughness determined immediately after the crop has been cut. In particular, in the case of a crop that is inhomogeneous in terms of ripening, Such a control is advantageous for the current crop stock. Straw toughness is also an important parameter for the intake device as well as for a threshing unit and a straw chopper on the harvesting machine, so that these components can also be advantageously controlled depending on the determined straw toughness.
  • Another advantage of the solution is that non-grain components are examined at cutting height.
  • the plants can be very dry in the upper area and very moist and therefore tough in the lower third. Undergrowth can only grow a few centimeters above the cutting height.
  • the properties of the plant parts in the lower third of the growth height are often not taken into account enough.
  • these plant properties often have a significant influence on the threshing properties and the grain quality.
  • the statement "ten centimeters more cutting height can result in up to 1% less grain moisture" is often true, which is not scientifically proven and certainly does not apply in dry, crumbly stands.
  • tough straw impairs threshing properties and ultimately also machine performance. Therefore, especially in difficult harvesting conditions, it can be advantageous to take a closer look at the stand at cutting height and to adjust the threshing elements and cutting unit based on these parameters, for example by raising the harvesting attachment when there is undergrowth.
  • the agricultural harvesting machine has in particular a harvesting attachment whose mowing and intake device cuts the crop and then immediately collects it.
  • it is not a so-called swath mower, which deposits the cut crop for later collection.

  • a detection axis over which the reflected light falls in a straight line into the detection unit then encloses an angle of, for example, 45 degrees with the ground. At a steeper angle of, for example, more than 55 degrees, more light reflected from the ground reaches the detection unit. At a flatter angle of, for example, less than 35 degrees, only light reflected from the upper part of the plant stubble and from plant stubble further away reaches the detection unit. However, the plant stubble is preferably detected over as much of its length as possible and in the immediate vicinity of the detection unit.
